Donatist

Member of a puritanical Christian movement in 4th-and 5th-century North Africa, named after Donatus of Casae Nigrae, a 3rd-century bishop, later known as Donatus of Carthage.

The Donatists became for a time the main Christian movement in North Africa; following the tradition of Montanism, their faith stressed the social revolutionary aspects of Christianity, the separation of church from state, and a belief in martyrdom and suffering. Their influence was ended by Bishop Augustine of Hippo; they were formally condemned 412.
